Procedure

In water:ethanol:toluene (1:1:10, 18.0 ml) were dissolved 4-ethoxyphenyl borate (252 mg) and 7-bromo-1-methyl-N-[4-[[N-methyl-N-(tetrahydropyran-4-yl)amino]-methyl]phenyl]-2,3-dihydro-1-benzoazepine-4-carboxamide (613 mg), and to the mixture was added potassium carbonate (420 mg). The mixture was stirred under argon atmosphere for 30 minutes, and to the mixture was added tetrakistriphenylphosphine palladium (59 mg). Under argon atmosphere, the mixture was refluxed for 17 hours. The mixture was diluted with ethyl acetate (200 ml) and washed with water (50 ml) and saturated brine (50 ml). The organic layer was dried with anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified with silica gel column chromatography (75 g, ethyl acetate:ethanol=9:1) and recrystallized from ethanol to give 7-(4-ethoxyphenyl)-1-methyl-N-[4-[[N-methyl-N-(tetrahydropyran-4-yl)amino]methyl]phenyl]2,3-dihydro-1-benzoazepine-4-carboxamide (Compound 306) (230 mg, 35%).
